Genome divergence between European anchovy ecotypes fuelled by structural variants originating from cross-hemispheric admixture

|
By Laura Meyer, Pierre Barry, Alan Le Moan, Christine Arbiol
| BioRxiv
Abstract The formation of ecotypes is shaped by mechanisms that reduce gene flow through complex interactions between ecological, historical, and genomic factors. In the European anchovy (Engraulis encrasicolus), marine and coastal ecotypes have been identified in the North-East Atlantic and Mediterranean Sea, yet the genomic basis of their divergence remains unclear.

Ecotype formation in the European anchovy fuelled by structural variants of different origins and genetic interactions with a southern lineage

|
By Laura Meyer, Pierre Barry, Rita Castilho, Christine Arbiol
| BioRxiv
Abstract The speciation of ecotypes can unfold in diverse ways and likely depends on multiple processes. The variants involved in ecotype divergence can include new mutations as well as older allelic variation that evolved in different contexts. Among the different types of variants that can contribute to reproductive isolation between ecotypes, structural variants (SVs) represent likely candidates due to their ability to protect divergent haplotypes from recombination and gene flow.
